Reverse sneeze syndrome is characterized by a series of rapid, loud,
forced inhalations through the nostrils, lasting anywhere from 10
seconds to 2 minutes. Attacks occur on a sporadic, unpredictable basis.
Dogs usually have the head
extended forward and stand still during the episode. Affected dogs
appear completely normal
before and after the attack. There is no loss of consciousness or
collapse, though sometimes the appearance of the dog is upsetting to
owners. Many dogs have
these attacks throughout their lives. The exact cause of reverse
sneezing is unknown, but it may be associated with sinusitis and other
upper respiratory disorders.
Many believe affected dogs are consciously removing mucus from the nasal
passages. In fact, many dogs swallow at the end of the attack. Whatever
the cause, the
condition is usually not serious. If the condition appears suddenly in
an older dog or if episodes become more severe or frequent, the nasal
passages and throat
should be examined.

Important Points in Treatment

Treatment is not necessary when the episodes occur infrequently on a
random basis.

Home treatments that have been reported to be successful include
massaging the throat, blowing in the nose, and rapidly and lightly
compressing the chest.
